Definitions

  • the present invention relates to (pyrrolidin-2-one-1-yl)acetamides of general formula (I) wherein R is hydrogen or hydroxyl and R1 is selected from the group consisting of: 2-aminoethyl, 2-[N-(pyrrolidin-2-one-1-yl) acetyl] aminoethyl, 2-hydroxyethyl, (glycerophosphorylethanolamino) carbonylmethyl, 1-trimethylammonium-3-carboxy-2-propyloxy-carbonylmethyl chloride, 1-trimethylammonium-3-carboxyisopropyl, and 3-pyridylcarbamide.
  • R is hydrogen or hydroxyl
  • R1 is selected from the group consisting of: 2-aminoethyl, 2-[N-(pyrrolidin-2-one-1-yl) acetyl] aminoethyl, 2-hydroxyethyl, (glycerophosphorylethanolamino) carbonylmethyl, 1-trimethylammoni
  • the compounds (I) are potent enhancers of learning and memory.
  • the present invention also relates to orally or parenterally administrable pharmaceutical compositions for enhancing learning and memory, comprising a novel compound of formula (I) as active ingredient.
  • the compounds of the present invention are more potent than these known compounds.
  • the compounds of formula (I) are prepared via a process illustrated in the following synthesis scheme.
  • a halogenating agent such as thionyl chloride or oxalyl chloride
  • a condensating agent such as dicyclohexylcarbodiimide (DCC), carbonyldiimidazole (CDI), 2-ethoxy-1-ethoxy-carbonyl-1,2-di
  • the activated compound (III) is reacted with a stoichiometric or excess amount of amine (IV) in a solvent-free phase or dissolved in an inert solvent such as acetonitrile or methylene chloride, or - if EEDQ is used as activating agent - in acetonitrile-water.
  • the raw reaction product is purified by silica gel chromatography with CH2Cl2-MeOH, CHCl3-MetOH or AcOEt-MeOH gradient.
  • Ethanolamine (1.943 g, 0.0318 moles) was added to (pyrrolidin-2-one-yl) methyl acetate (5 g, 0.0318 moles) and the mixture was kept under stirring for 20 hours at room temperature.
  • the raw reaction mixture was chromatographed on silica gel using EtoAc-MeOH as eluant, ratio 8:2.
  • CDI (4.1 g, 0.025 moles) was added to (pyrrolidin-2-one-1-yl) acetic acid (3 g, 0.021 moles) in 75 ml of CH2Cl2 and the mixture was kept under stirring for one hour at room temperature. Nicotinoylhydrazide (2.9 g, 0.021 moles) was added to the mixture and the solution kept under stirring for 20 hours at room temperature. The raw product obtained by evaporation of the solvent was chromatographed on silica gel using EtOAc-MeOH as eluant, ratio 9:1. The product thus obtained was crystallized from ethyl ether.
  • EEDQ (18.54 g. 0.075 moles) and H2O up to complete solubilization of the mixture were added to 7.21 g (0.05 moles) of (pyrrolidin-2-one-1-yl) acetic acid in 150 ml of CH3CN under stirring. After 30 min (R,S)-aminocarnitine dihydrochloride (9.8 g, 0.042 moles) (prepared as described in J. Biol. Chem. 269, 14748, 1985) and triethylamine (8.59 g, 0.084 moles) were added and the solution kept under stirring for 60 hours at room temperature.
  • CDI (2.675 g. 0.0165 moles) was added to a suspension of N-[2 (pyrrolidin-2-one-1-yl)acetyl]glycine (3.007 g, 0.015 moles) in THF (30 ml) in nitrogen atmosphere and under stirring at room temperature. After 30 min, carnitine benzylesther perchlorate (2.642 g. 0.0075 moles) in THF (30 ml) was added and the reaction mixture kept at room temperature for 24 hours. The THF was decanted and the residue taken up 4 times with 25 ml THF that was removed every time by decantation. The residue taken up with MeOH was percolated on weak basic resin A21, eluting with MeOH.
  • the water-soluble compounds were dissolved in saline; the insoluble ones were dissolved in dimethylsulfoxide and then diluted in 2% Tween®80, ratio 1:4.
  • the apparatus for passive avoidance conditioning was a black plastic chamber (42X42 em, height 40 cm) provided with a floor constructed of metal rods that could be electrified. From the front wall extended a white runway, 30 cm long and 10 cm wide provided with side walls 12 cm high, which led into the box through a guillotine door. The runway was lightened by a 60 W lamp (cfr. Ader et al., Retention of passive avoidance response as a function of the intensity and duration of electrick shock. Psychon. Sci .; 26 (3), 125-127, 1972).
  • the mouse was then removed from the chamber and immediately administered an electroshock delivered through spring clips attached to the ears (square wave, intensity 20 mA, amplitude 0.6 msec, duration 0.5 s, frequency 50 Hz).
  • an electroshock delivered through spring clips attached to the ears square wave, intensity 20 mA, amplitude 0.6 msec, duration 0.5 s, frequency 50 Hz.
  • the animals were administered the compounds under examination and scopolamine (1.0 mg/kg s.c.) 30 and 15 minutes, respectively , before they were placed on the runway. The test then continued as previously described. In both tests, retention was assessed 24 hours later by placing the animal on the runway and again evaluating the latency in entering the chamber, using an end-point of 300 s (cfr. Bammer, loc cit.).
  • the behavioural profile was assessed in Swiss albino male mice weighing 22-24 g, using the Irwin test (IRWIN S., Drug screening and evaluative procedures. 136 , 123-128, 1962). The animals had been caged under normal conditions and kept fasting for the last 18 hours. Following administration of the compounds, the behaviour of the animals was monitored for 6 hours.
  • the animlas of the control groups were administered water (10 ml/kg i.p.).
  • ST 625, ST 630, ST 635, ST 645 and ST 650 did not alter, at the tested doses, the behavioural profile.
  • the analgesic activity was assessed in Albino Swiss mice weighing 22-24 g, utilizing the hot plate test (57°C).
  • the animals kept under normal caging conditions and kept fasting for 18 hours, were placed on the hot plate for 30, 60 and 120 minutes following the administration of 100, 25, 6 and 1.5 mg/10 ml/kg of each compound under examination.
  • the analgesic activity was assessed by measuring the increase (in seconds) of the time the animals continued to stay on the hot plate. None of the tested compound was shown to possess analgesic activity.
  • the compounds of the present invention can be formulated into orally or parenterally administrable pharmaceutical compositions. Suitable excipients and compositions for tablets and vials are illustrated in the afore-said Canadian patent 1,100,515.
  • compositions in unit dosage form comprise between about 100 and about 500 mg of active ingredient.
